Summary of BIOS Whitelist Removal Problem
Problem:
I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
Initial Findings:- My current BIOS version is N1KET58W (1.45).
- I have a CH341A programmer and have successfully created two full backups of my BIOS.
- I have the ability to use command-line tools on a Linux machine.
- I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.

Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.
2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.
The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but... -
I've searched and read Beginners guidelines and other sticky threads. This is just a simple bios question. If I may, I'm having trouble finding any help, including from lenovo tech support & forum, for how to get usb boot to list in boot options. I'm trying to run memtest86 so nothing as highfaluting as re-install, flash a bios, etc.
I've made usb boot enabled and secure boot is disabled. I can find no other option in bios ver LZCN34WW (the original bios). Would anyone here be familiar with LOQ or Legion bios versions & know what is going on?
TY,

Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
My Lenovo Legion Y540 (i7-9750H, RTX 2060) bricked after I downgraded from BHCN44WW to BHCN21WW.
Laptop stopped booting entirely.
I used a CH341A programmer to dump the corrupted 16MB BIOS.
i then attempted the following:- Downloaded stock BIOS BHCN39WW from Lenovo
- Trimmed it to 16MB
- Extracted the BIOS region from the corrupted dump
- Extracted the BIOS region from the stock 39WW
- Replaced the corrupted BIOS region with the stock one (within hxd , opened the corrupted dump and replaced its region by the stock)
- Injected back my LDGB / DMI
